8" vs. 9" convertor

A 124 MPH well prepare car should go 10.5ish and 1.3 to 1.4 @ 60

5200 RPM in Traps = I would be looking for another tack unless you
were at 1/8 mile.

Our little Red 68 Valiant small block street car that won the MATS Street
Legal Class last week has 3:91 and a 29 tires at 120 MPH was 6250 thru lights!

I am going though the traps in overdrive. 4.56 + GVOD = 5,200@124
